At which location in Earth's interior exhibits a change in

uranmaximum [27]

Answer:

The Earth's interior exhibits a change in trend in the "outer core."

Explanation:

The 4 Main Layers of the Earth

1. Crust - This is the outermost layer of the Earth. It consists of igneous, metamorphic and sedimentary rocks. This makes the crust rock solid.

2. Mantle - The mantle is formed by silicate rocks. It is located between the crust and the outer core. It consists of the upper mantle and the lower mantle. The upper mantle lies between the crust and the lower mantle while the lower mantle lies between the upper mantle and outer core.

3. Outer Core- This is the only liquid layer of the earth. It is mostly made of iron and nickel. This causes a change in trend among all the other parts of the Earth which are solid.

4. Inner Core- This is the innermost part of the Earth. The temperature here is hotter than the sun. The solid inner core is said to be growing at the expense of the outer core. This also has the highest density of all.

Balance each of the following redox reactions occurring in basic solution.MnO−4(aq)+Br−(aq)→MnO2(s)+BrO−3(aq)Express your answer

Ahat [919]

Answer : The balanced chemical equation is,

$2MnO_4^-(aq)+Br^-(aq)+H_2O(l)\rightarrow 2MnO_2(s)+BrO_3^-(aq)+2OH^-(aq)$

Explanation :

Rules for the balanced chemical equation in basic solution are :

First we have to write into the two half-reactions.
Now balance the main atoms in the reaction.
Now balance the hydrogen and oxygen atoms on both the sides of the reaction.
If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the more number of oxygen are present.
If the hydrogen atoms are not balanced on both the sides then adding hydroxide ion $(OH^-)$ at that side where the less number of hydrogen are present.
Now balance the charge.

The half reactions in the basic solution are :

Reduction : $MnO_4^-(aq)+2H_2O(l)+3e^-\rightarrow MnO_2(s)+4OH^-(aq)$ ......(1)

Oxidation : $Br^-(aq)+6OH^-(aq)\rightarrow BrO_3^-(aq)+3H_2O(l)+6e^-$ .......(2)

Now multiply the equation (1) by 2 and then added both equation, we get the balanced redox reaction.

The balanced chemical equation in a basic solution will be,

$2MnO_4^-(aq)+Br^-(aq)+H_2O(l)\rightarrow 2MnO_2(s)+BrO_3^-(aq)+2OH^-(aq)$
